Description

write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnn writes the k-NN classifier for an OCR task with the OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle to the file given by FileNameFileNameFileNameFileNamefileName. If a file extension is not specified in FileNameFileNameFileNameFileNamefileName the default extension '.okc'".okc"".okc"".okc"".okc" is appended to FileNameFileNameFileNameFileNamefileName. write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnn is typically called after the classifier has been trained with trainf_ocr_class_knntrainf_ocr_class_knnTrainfOcrClassKnnTrainfOcrClassKnnTrainfOcrClassKnn. The classifier can be read with read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnn.

Result

If the parameters are valid, the operator write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
